Welcome to Refiner. Refiner improves your writings. It corrects grammar issues, adjusts tone, and offers formatting options. I found it useful for non-native speakers and professionals who communicate with text. Here's a quick demo: - Replace this text with your own. - Optionally, choose tone and refinement instructions. - Click the 'Refine' button. - Watch as Refiner improves your text. - Copy the result to your clipboard. It is an open-source project. The code is available on https://github.com/imankulov/refiner. Give it a try now.
